Made the booking for a colleague and this is the review he provided:
The GOOD: The place is reasonably priced and, as advertised, quite close to public transportation. The neighborhood is sound and has reasonable,
non-touristy-priced food. The host is a good communicator and is quite knowledgeable of Bangkok.
The BAD: Although reasonably priced as a unit comparable to others, and while the listing spells this out and Evan did ask us to confirm that we understood the electricity pricing, the electricity pricing is something guests should be aware of. The government billed rate is 5 baht per unit. The host charges 10 baht per unit. If you are working from your unit, renting long-term, or otherwise spending lots of time inside running appliances, this will add up very quickly. While this might not bother everybody, if on a budget, this is something to consider when booking.
